- Insurance usually doesn’t cover termite damage.
Anyone in Gastonia who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 31°F slow termites near the surface around Gastonia, but they move deeper and keep feeding under heated homes. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.
- 1Wood that sounds hollow when tapped.
- 2Winged swarmers indoors, especially in spring.
- 3Live pale insects inside a broken mud tube.
- 4Small kick-out holes in exposed wood.
- 5Doors and windows that suddenly stick.
- 6Discarded wings caught in spider webs.
Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.
- Damage hides behind drywall, flooring and trim.
- Homeowners insurance usually doesn’t cover termite damage.
- An active infestation can complicate a home sale.
- Formosan colonies are large and can do serious damage quickly.

It nests in soil and builds mud tubes to reach wood. It needs steady moisture. Formosan termites have turned up in parts of North Carolina. They're less common. Their colonies are much bigger, though. The termite you're most likely to meet in Gastonia is the eastern subterranean termite.
Local termites conditions in Gastonia.
Across Gastonia, the area is mostly suburban, so termites pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by. An inspection in Gastonia usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Gastonia's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. A provider who works Gastonia and North Carolina every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options. Gastonia sits in a humid subtropical climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.When termites swarm here.
Across Gastonia, eastern subterranean termites usually swarm from March through May, typically on a warm, sunny day after rain. Across Gastonia, formosan termites in North Carolina swarm later, from late April into June. Look for them on warm, humid evenings around porch lights. A swarm outside means a colony is nearby. A swarm inside usually means it's in the house. Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves.
Where to look around your house.
Take a flashlight underneath. Check the piers, the sill plate and the floor joists. Standing water or a musty smell needs fixing either way. The same advice applies across the area, from Gastonia out to Charlotte and Huntersville. A lot of houses around Gastonia are built over crawl spaces, and that's usually where termites start.
A year of termites in Gastonia.
- Winter: a good time to book an inspection in Gastonia, before swarm season starts. - Spring: swarm season. Across Gastonia, expect it from March through May. Check windowsills and light fixtures for wings. - Summer: with highs around 89°F in Gastonia, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 46 inches of rain a year in Gastonia, make sure gutters and downspouts carry water well away from the foundation.
What happens at an inspection.
The inspector walks the outside of the house first. They check the foundation, the soil line and nearby wood. Inside, they check the garage, baseboards, plumbing gaps and the attic. They'll also go into the crawl space. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help. Most inspections take an hour or two.
Termites or ants?
- Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Wings: termite wings are all the same length. Ant wings aren’t. - Waist: termites are thick through the middle. Ants are pinched. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Debris: termites leave mud. Carpenter ants leave sawdust.
Getting ready for treatment day.
Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines. Keep kids and pets inside while the Gastonia crew applies the product, and ask how long to stay off treated soil. In North Carolina, native species begin swarming in late winter and continue into September or October, usually during the day on warm days following rain (NC State). Drill holes in slabs or patios get patched afterward. Prep is light for liquid treatments and bait stations.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in Gastonia that means extending downspouts and pulling mulch back from the slab. Wood chips touching the siding trap the moisture termites are after. Pull mulch back from the foundation and keep the layer thin.
Questions to ask before you sign.
- What do I need to do before and after treatment? - Which termites did you find, and where? - What product or system will you use? - Is the whole foundation treated, or just one spot? - What does the warranty cover, and for how long? - What does the yearly renewal cost?
What affects the price
- Number of bait stations required.
- Extent of existing damage needing repair.
- Local labor rates and licensing requirements.
- Linear feet of foundation to be treated.
- Cubic footage under the tent for fumigation.
- Attached garages, decks, and additions.

What's your biggest concern about termites?
When to call for help
Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud. Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way.
What you can do yourself
Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house. Treating an active colony is harder. The product has to reach the whole colony. It also needs even coverage around the entire foundation. Store-bought sprays usually kill only the termites you see.

Simple ways to keep termites away
- Use borate-treated or pressure-treated lumber for repairs.
- Keep mulch at least a foot from the foundation.
- Screen attic and foundation vents with fine mesh.
- Trim shrubs so foundation walls stay visible and dry.
- Never leave form boards or scrap lumber in the soil.
- Keep the termite renewal contract current after treatment.
An inspection starts outside, with a flashlight along the foundation line where mud tubes show up first.Did you know?
Across Gastonia, a termite queen can keep laying eggs for 25 years or more.
Questions people ask
Do I have to leave my house during termite treatment?
Not for a soil treatment or bait stations. Fumigation is different. Everyone leaves for two to three days, pets and houseplants included.
How long do termite bait stations take to work?
Usually several weeks to a few months. Termites have to find the stations first. Then the bait spreads through the colony.
Can I treat termites myself?
Prevention, yes. An active colony is harder. The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see.
Does fumigation kill subterranean termites too?
Not reliably. Tenting clears termites inside the house. It doesn't reach a colony living in the soil.
Can termites damage a house on a concrete slab?
Yes. They come up through expansion joints, plumbing gaps and small cracks. Inspectors check those spots first.
Can you treat for termites before building a house?
Across Gastonia, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Gastonia, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
Are termites common in North Carolina?
Around Gastonia, the usual culprit is the eastern subterranean termite.
